Ashlee Simpson and Evan Ross wed

The couple exchanged vows on Sunday during a private ceremony at the Greenwich, Conn., mansion of the groom’s mom, Diana Ross, according to multiple reports.

The bride’s newlywed sister Jessica Simpson served as Ashlee’s matron of honor, almost two months after her own wedding to husband Eric Johnson, while her kids Maxwell, 2, and son Ace, 14 months, took on the roles of flower girl and ring bearer, respectively.

Bronx Mowgli, Ashlee’s 5-year-old son with ex-husband Pete Wentz, walked his mom down the aisle.

This is actor Ross’ first marriage and the second for Simpson, who was married to the Fall Out Boy rocker from 2008 to 2011. Ross proposed to Simpson in January after just six months of dating.
